Sealed for All: Multi-Party Confidential Computing, No Trust - Ryota Hashimoto & Takahiro Kambara, NTT
As cross-organizational data collaboration becomes central to modern computing, protecting sensitive data and proprietary code during joint processing is a growing challenge. Confidential Computing (CC), based on hardware-enforced Trusted Execution Environments (TEEs), enables data to be processed securely without being exposed. This session introduces "Multi-Party Confidential Computing (MPCC)," a concept where multiple data providers and application owners contribute their assets to a shared computation while keeping both data and applications confidential from one another. Rather than relying on access control or mutual trust, this model uses TEEs and file encryption to enforce runtime isolation between parties. The speakers will show how key mechanisms — attestation coordination across multiple TEEs, auditability after execution, and isolation from the underlying cloud — can be realized with open source technologies including Kata Containers and Confidential Containers.
